I've checked the threads and done a search and I don't *think* this has been covered before, but aplogies if it has.
I've just had an old open CH system with hot water tank replaced by a closed combi boiler system (Vaillant ecotec 831). The system was powerflushed as part of the installation.
Following the install the system is rapidly depressurising from 1.2bar down to 0.2 bar in about 90 minutes. My plumber's been back to check all of the pipework that they did during the install and there are no leaks there so he's suggested that there's a leak somewhere else in the system. All of the radiators seem intact so I guess it's a leak in the pipeework somewhere, but where?
There's no water dripping through the ceiling so I figure the leak must be downstairs in the pipework. Unfortunately it's a newish house (about 30 years old) and the floors are solid concrete as far as I can tell.
Do you think that this is a leak, and if so, how the hell can I find where it is for my plumber to sort out? His suggestion was to run the system with the water inlet valves open enough to let water in at the same rate it's leaking out, and then look for the wet patch!
Thanks in advance for any help.
